About the Charging/Communications Cradle
When the Charging/Communication Cradle (the cradle) is attached to AC (or to vehicle 
DC) power and the monitor is seated in the cradle (Figure 9), the cradle does the 
following: 
• Recharges the monitor battery, whether patient monitoring is occurring or not.
• Powers the monitor, conserving the charge on the monitor battery.
• (If the cradle has the USB data transfer option) enables data transfer between a 
PC and a monitor . See “About the USB Data Transfer Option” on page 17.
The cradle is intended to hold the monitor when the patient is in bed or is otherwise 
stationary. The cradle can sit on a flat surface near the patient, attach to the bed rail (using 
the bed-rail hook), or hang from an IV pole (using the optional IV Pole Mount accessory).
If the monitor is in the cradle and the AC power adapter is connected to the cradle, the 
monitor runs on AC power rather than battery power. This keeps the monitor battery at full 
charge so that it can then run under battery power when it is removed from the cradle to 
accompany the patient away from the bed.
The cradle can be connected to AC power at all times, whether the monitor is present or 
not.

WARNING  Never download a configuration file to the monitor while you are 
monitoring a patient with the monitor in the cradle. 
• Communication with the network (and Acuity) is interrupted if you download 
a configuration to the monitor or upload patient data from the monitor.
• Changing the monitor configuration shuts down the monitor and deletes all 
patient data from the monitor.
